Is massive abstract noun or common noun?

"Massive" is an adjective, while "noun" is a common term used in grammar to refer to a part of speech. An "abstract noun" refers to a concept or idea that cannot be physically touched, such as "freedom" or "happiness." In contrast, a "common noun" refers to general items or people, like "dog" or "city." Therefore, "massive" itself is not a noun but describes the size or extent of nouns.
